Would it be best for the country?
The way I look at it: What is best for the country is always a complex question at any point of NORMAL time. There are always contrarian views and many of them; and there is never a clear acceptable answer. No 'correct' answer ever pans out over time to be the correct one.
What is happening in the country today is NOT any normal time. Donal Trump has been attacking this country's democratic systems for years. Republican party, most of their leaders have been supporting him for last 4 years thinking 'that's best for the country' and in most cases, best for their pockets and power. (Not that Dems won't do that if they were in power - it's a cyclical thing of roulette of power). Look where we are today by following what one party thought was the best for the country.
What or who was thought to be best for the country has attacked the country - from within - in real terms.
So I say and I hope you would agree it is not a normal time! Last time we were 'invaded' like this was more than centuries ago and by the British.
This man has announced an war against our country and is delivering on it! So responses should be fitting a war like response. No amount of punishment will be enough to deal with this. So anything - impeachment to imprisonment on charges including inciting terrorism, and doubling down on them to prevent any future copy-thug to save the country will not only be the best for the country, it is the only thing that needs to be done to save this democratic republic we live in.
That's of course, if we want to keep it democratic and country of laws.
P.S. What i am wondering about is why Republicans are not punishing him so that Democrats don't have to ?
